xchaotic··on For Online Courses, Questions Over How Success is Measured (2014)
I was recently watching some courses on AWS, I passed the actual exam but I only watched a few videos where things were a bit ambiguous for me. So the completion metric is not very useful or accurate IMO.
xchaotic··on Homebrew removes MongoDB from core formulas
Define production and define HTTP3. The beauty of open source is that you can be already serving pages using QUIC and TLS1.3 while the standard is being finalised.
xchaotic··on Homebrew removes MongoDB from core formulas
I think you got it backwards. A relational schema change is required and probably a data reindex or reload when you change a data model so relational is the least flexible as opposed to something like Mongo nosql?

How do you know someone is a vegan? They write an NYT article about it.
xchaotic··on Android 10: Google Confirms 193 Security Vulnerabilities Need Fixing
Google fixing vulnerabilities even before the release can only be good news, but one does have to be wonder why a whole class of such vulnerabilities are even allowed after so many releases?
xchaotic··on Levenshtein Distance
We have implemented and using this in MarkLogic:

xchaotic··on GitHub Outage Currently Ongoing – Issues, PRs, Notifications
Justyna yesterday I was complaining about GitHub monoculture in the context of Atlassian sunsetting Mercurial. Outages like this are normal, but the problem is lack of good competitors.
xchaotic··on Ceramic-bearing bicycle drive shaft (2018)
Scientific measurements or it didn’t happen. I think wax underperforms lube, prove me wrong.
xchaotic··on The We Company S-1
Did Euclid / WeWork realise that many people prefer to work from home? My past 14 years of professional experience would net WeWork 0 rental income.
xchaotic··on Interest Rates: Naturally Negative?
Obviously this article shows up when the negative rates are already here, with the benefit of hindsight. What I am more interested in at this point is what is a good, safe alternative for a small time investor who’s already overweight on equities and housing. Bonds used to be the sensible pillar that worked at times when stock market crashed and now it doesn’t really make sense to use them for a small guy.
xchaotic··on Coinbase: Responding to Firefox 0-days in the wild
This point to an actual use of the cryptocurrency - exploiting a 0 day against someone who might have a crypto wallet means you can actually directly make money off exploits. Prior to crypto, having a 0 day wasn't equal with ability to make blackhat money with it...
xchaotic··on 20-Year Mortgages Hit Zero for First Time in Danish Rate History
Why would people not buy extra properties with these mortgages “just in case”? Especially the 10 year one seems low risk and worst case you have a property after 10 years?
xchaotic··on 20-Year Mortgages Hit Zero for First Time in Danish Rate History
Hmm FED rate is NOT negative?
xchaotic··on One job, many roles: The different skills needed to be a successful CTO
As a CTO I’d probably hire the guy. OTOH I probably would not let prod be touched in the first place.
xchaotic··on Rocket Lab - Reusability Plans for Electron Rocket via Helicopter Catching
Is this really the most simple available method?
xchaotic··on Documentation – Your Secret Weapon
Without context, I have no idea what are you trying to imply or document with OPTION?

I can more or less figure out what the code does, but not why it does it. Here you should document why are you grepping for something

xchaotic··on A Commercial Path to Fusion
What I find particularly troubling about the design of tokamak reactors is that on one hand you have magnets that need to be cooled to -250C or whatever the “high” temperature is nowadays and in the middle of it you have plasma that will leak thermal radiation in any way possible. The magnets themselves will heat up from running large electric currents through them. This just feels like a recipe for a disaster - if things suddenly stop working, due to heat or otherwise you have a very hot, radioactive plasma trying to equalise its energy with the outer world...
xchaotic··on Why I Turned Down an AWS Job Offer
It's a bit like this: if the pay is too low, you make the jump to get the money. If the money is good, you wait a few years and make a jump anyway because hopefully by then you've saved enough to be set for life (assuming normal pay elsewhere)
xchaotic··on Show HN: A time tracker that asks you every 10 min what you're doing
Obligatory “I’m updating the tracker every 10 minutes “

Why would you do it to yourself? It’s yet another distraction for any deep work.

xchaotic··on Boeing changing Max software to use two computers
High speed jet fighters flying above Mach speed doesn’t really compare with a chubby airliner flying 900km/h?
xchaotic··on Bad Times in Tech? Not If You’re a Startup Serving Other Startups
Old BigCo is good enough for the good times and even better for the bad times hopefully eh?
xchaotic··on Alphabet overtakes Apple to become most cash-rich company
Why not a PS4 hardly more expensive at this point?
xchaotic··on Alphabet overtakes Apple to become most cash-rich company
There’d be almost the same amount of electronics just sitting in Google’s servers. People don’t game 24/7 but if Google want to provision for peak loads like Christmas they can’t really get away with having less?
xchaotic··on Alphabet overtakes Apple to become most cash-rich company
Single player so I assume it streams fine. With multiplayer and the other side deliberately cheating it is not going to work. Can’t beat physics
xchaotic··on The Death of the Mom and Pop E-Store
Any quote or source for this? I think companies get efficient when they have to compete and some of that stays when they become monopolies
xchaotic··on Want to hire the best programmers? Offer growth
Even with paying the accountant and even if the higher bracket was 90% you’d still be making more by earning more. It’s hard to agree with your line of thinking but I have seen this often that people are willing to sacrifice quite a lot of money for “security” and “peace of mind”. In practice you’d have more peace of mind with more money in the bank.
xchaotic··on Manual Work is a Bug – Always be automating (2018)
we may have plateaued by now, but so far it's still a net gain - a new person comes in, learns things, often by reverse engineering, often improves the automated process, sometimes leaves etc. But what we do need is a better way to measure automation gains and losses - basically any process that is automated shows up as a net loss in human productivity, which is simply not true. And vice versa any automated processes probably don't account correctly for the total energy and resource use and the cost of maintenance (both software and hardware).
xchaotic··on What senior engineers do: fix knowledge holes
There is job title inflation and my company hires at Senior Eng as the lowest level.
xchaotic··on How I encrypt my data in the cloud
"$4 per TB/month" so 16 X 12 = $192+tax not a insignificant amount even in a first world country and probably a deal breaker for people living in poorer countries.
xchaotic··on Why Didn’t Denmark Sell Greenland?
quality sand is incredibly abundant and cheap everywhere I lived. It wouldn't be economically feasible to export sand from Greenland.
